Light weight, Hydraulic drilling machine for grouting hole drilling

Suitable work in the narrow environments

KDY-30H

1.APPLICATION

KDY-30H hydraulic drill rig is a multi-function drill rig developed facing drilling grouting  hole for hydro-power station. It also can be used for drilling the hole of support, penetration-proof, blasting; and treating dangerous rock and hillside. It is mainly suitable for drilling hard rock with diamond bit and PDC bit, and DTH drilling as well.

2.FEATURES

-Reasonable specification, assure more efficiently drilling;

-Fully hydraulic drive, top-drive head rotation, feed and hoist are all done by ration pump and ration motor which composite independent open hydraulic system, it is simple, advance, easy to use and maintain;

-The main hydraulic components are from world famous hydraulic manufacturers, two-step filtering, to assure the reliability of the hydraulic system;

-Newly-designed structure, three speeds, and can get different speeds through changing oil motor of top-drive head, to satisfy the needing of different drilling technology;

-Light weight, easy to move, re-assembly and maintain. Especially suitable for drilling in tunnel and on the frame.
